Bernie Sanders makes moves pointing to a possible 2020 run

Senator Bernie Sanders' moves might be leading him to the 2020 presidential race.

Since losing the 2016 primary to Hillary Clinton, Sanders has spent time getting closer to the labor movement, beefing up his foreign policy credibility, touring the country to promote his political group, Our Evolution, and fighting along Democrats against Donald Trump’s administration.

Everything seems to be pointing at a possible run for 2020, but Politico reports the Vermont independent hasn't yet decided if he will run for president again.
